The table below lists the capture threshold levels, based on the probe in use (for
the current channels) and voltage at the different percent selections.

Voltage
Transients are detected by comparing all 256 samples on the current cycle with
their counterparts from the previous cycle for each active input channel. Should
any one sample deviate from its counterpart by the selected percentage value in
the set up, this will be considered a transient and the data will be captured.
When capture occurs, four cycles are recorded for each input. These include the
trigger cycle, the previous cycle to the trigger and the two cycles that follow the
triggered cycle. All active inputs will be captured.
